Jeld Wen bifold door- cut down?

Can I cut off 1 inch from top and bottom of door panels to make it fit
existing opening (i guess the builder must have done this when the
house was built) ? Is the top wood rail of the door wide enough to
give up 1 inch and still hold the pins? thks bill

The pins normally will be in the end of the vertical stile, not just
through the horizontal. If they don't fit, thought, what have you lost?
I have cut hollow doors down substantially and fitted new ends in them
though, so even if you have to do that it is possible.

thanks. so the vertical stile is probably solid? maybe i'll drill
small pilot holes in the back to confirm. after i cut it down i
still need enough solid material to hold the guide pins. u think i
can take the full 2 inches just off the bottom? make it easier...
thks bill

They're a box w/ a skin and typically a cardboard crossframe interior.
Normally also you can see the end and top rail joint looking at the end
to see how wide a piece it is and whether the pins are in it or the
horizontal.
Sure you can take all off of one end, but you'll be guaranteed to have
an open end if you do. (Of course, you'll probably have a pretty thin
end piece if you take an inch off either end, too... :) ).
As I say, if they're 2" too long, you haven't lost much unless they're
new and could be returned which would seem unlikely...

If these are typical hollow core doors, leave the tops alone.
Score cut through the veneer to avoid splintering. Cut what you
need at the bottom. Take an appropriate size stick to push the
cardboard filler up into the door just a bit. Use a sharp chisel
or whatever to clean the veneer, etc off the original door bottom
stile. Glue, insert, and clamp.

Dan you r the man. thanks. worked like a charm. i cut off 2 and
1/16 off the bottom. instead of using the original medium density
fiberboard which like u said would need cleaning, i cut new bottoms
from 1x pine. thanks again, bill
